ACETYLENE-GAS GENERATOR.

Application filed November 14, 1922. Serial No. 600,895.

To all whom it may concern:

Be it known that I, OSCAR MAXoN, a citizen of the United States, residing at Cadiz, in the county of Trigg "and State of Kentucky, have invented new and useful Improvements in Acetylene-Gas Generators, of which the following is a specification.

This invention relates to acetylene gas generators, and comprehends a novel construction of means by which the carbide is automatically fed into the water receptacle, and the communication between the carbide container and the water container automatically cut OK when a predetermined quantity'of gas is generated within the apparatus.

More specifically stated, the invention contemplates the use of a slide valve which controls communication between the carbide container and the water receptacle, with means for automatically operating said valve incident to the rise and fall of'the bell operating within the gas receiving tank.

An object of importance :resides in constructing the slide valve operating means with a counterbalancing element, which operates to close the valve, should the valve operating mechanism become impaired for any reason whatsoever.

The nature and advantages of the inven tion will be better understood when the following detailed description'is read in connection with the accompanying drawings, the invention residing in the construction,

' combination and arrangement of parts as claimed.

In the drawings forming part of this ap plication, like numerals of reference indicate similar parts in the several views, and wherein: T p

Figure 5 is a horizontal sectional view through the carbide container.

Figure 6 is a sectional view taken on the line 66. of Fi ure 1, looking'in the direction of the arrow.

Referringto the drawings in detail, 10 indicates a waterreceiving receptacle, having associated therewith a funnel 11 which is supported upon the receptacle, and the neck thereof arranged within'the receptacle.

The funnel is used for the filling of the receptacle as will be readily understood. Arranged above and supported by the receptacle lO-is a carbide container 12 which is provided with a filling neck 13 normally closed by a cap 1 1. This container includes what may be termed an auxiliary container made up of a plurality of convergently disposed sides 15 which are arranged to provide a receptacle of rectangular formation in cross section. It is the auxiliary receptacle just referred to that actually receives and supports the carbide. One side 15 of the receptacle is provided with an opening 16, across which slides the valve 17 the latter of course controlling communication between the carbide container and the Water receptacle 10. The valve is automatically hereinafter described.

The gas receiving tank is indicated at 18 and spaced from the receptacle 10, and operating in this tank is the usual bell 19.

The gas generated within the receptacle 10 is conveyed to the tank '18, but passes through a filtering element 20 before entermunicating with the space between the outer wall of the carbide container,and the auxiliary container made up of the sides 15.

'The filtering element 20 is arranged adjacent the bottom' of the tank 18, and the gas subsequently passing through the filtering element is conveyed within the tank 18 by means of the pipe 23. Arranged in parallelism with the pipe 23, and within the tank 18 is a. second pipe 24: which passes from the lower end of the tank and communicates with a tubular container 25. Arranged in the container 25 is an absorbent material 26, 1

actuated and controlled in a manner to be' so that the gas passing from the tank 18 tothe supply pipe, through the container 25 is relieved of all its moisture, the latter being absorbed by the material 26.

The means for automatically controlling the slide valve embodies a horizontally-disposed lever 27 arranged above the apparatus, and fulcrumed at one end as at 28 upon a bracket arm 29 secured to the Water receptacle 10. Pivoted to the lever 27 and depending therefrom is a rod 30 arranged to reciprocate within a tubular member 31 which projects within the receptacle 10. The rod 31 is pivoted at its lower end to the adjacent end of a beam 32, the latter being tulcrumed at a point between its ends on a. suitable support indicated at 33. The support consists of a bar which is terminally secured to the receptacle 10, and is provided with an upstanding lug or ear 35 upon which the beam is pivoted. The opposite end of. the beam 32 is pivotally associated with a vertically disposed weighted rod 36, the latter operating within the carbide container, and connected at its upper end with the slide valve. The lever 27 cooperates with means carried by the bell 19, so that the lever is moved upon its fulcrum 28 incident to tne rise and fall of the bell, thereby controlling the movements of the slide valve which regulates the quantity of carbide which is admit-ted into the water receptacle 10. The valve is equipped with an agitator 37 which operates within the auxiliary carbide container defined by the sides 15 and in this way the carbide is freely passed through the opening 16 of the auxiliary container. .Arranged in the auxiliary container is a transverse bar 38 having a slot 38 through which the agitator operates. In this connection it is desired to be pointed out that the rod 36 is heavier than the rod 30, and serves to counterbalance the lever 27 in a manner, so that in the event the apparatus should become impaired for any reason whatsoever, the rod 36 would gravitate to a position which would effectively close the valve and thereby cut oil communication between the carbide container and the receptacle 10. The lever 27 operates between the spaced parallel members 37 which constitute a guide for said lever, and these rods are slightly bent or oifsct from an appropriate point in their length as clearly illustrated in Figure 6 for a purpose to be presently described.

A's herein above stated, the lever 27 cooperates with means associated with the bell 19, which imparts movement to the lever incident to the rise and fall of the bell. In addition to this fact, the means just referred to is designed to eilect a release of the lever 27 at a predetermined interval, in which instance the valve. is positively closed. The interval at which the lever is released occurs when a predetermined quantity of gas has been generated within the apparatus, so that the bell can rise independently of the lever to take care of an overcharge of gas. This means includes an arm 38 which is pivoted on the bell 19 and of a length to project a slight distance beyondthe bell as clearly illustrated in Figures 1 and 4. This arm 38 has freely pivoted thereon a catch 39 of substantially U-shaped formation in end elevation as illustrated in Figure 6, and further includes a cam-like portion 40. The catch normally straddles the lever 27, to impart pivotal movement to the lever incident to the rise and fall of the hell, but when a predetermined quantity of gas has been generated in the apparatus and the bell consequently elevated, an ap preciable degree, the valve will be closed to prevent the further discharge of carbide into the water receptacle 10. This is accomplished by reason of the lateral movement imparted to the lever 27 and the consequent disengagement of the same from the catch 39 when the lever has moved into the angularly disposed part 37 of the vertical guide 37, the catch 39 being carried in a vertical direction by the bell 19. hen a certain amount of the gas thus contained in the tank has been consumed and the pressure reduced, the bell gravitates within the tank, during which movement the cam shaped portion 40 of the catch 39 passes over the lever 27 in a way that allows the catch to again straddle this lever. As the bell tends to move downwardly withinthe gas receiving tank, the catch which is now associated with the lever lowers the latter and again opens the valve.

Passing through the funnel 11 is. a rod 4-1 which is journalled in a bearing 42 in the lower end of the receptacle 10. One end of this rod is offset as at 43 and movable across the bottom of the receptacle to agitate the sediment or that portion of the carbide that collects upon the bottom, while the upper end of the rod is equipped with a handle 44 by means of which the rod is actuated for the purpose stated.

While it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed.

Iaving thus described the invention, I-

claim:

1. In an acetylene gas generator including a carbide container having an outlet, a slide valve controlling the outlet, a water receptacle below the carbide container, a lever having one end pivoted at .a point above the water receptacle, spaced parallelv rods arranged within the water receptacle, a cross piece pivoted between its ends and termi nally connected to the adjacent extremities of the rod, one of the rods being pivotally connected with said lever, the other of said rods being connected to the valve, and an. agitator carried by the valve and. operating in the carbide container.
